nor-Loon Application filed November To all whom it may concern:

Be it known that 1, JOHN W. Snawvna, a citizen of the United States, residing in Portland, in the county of Jay and State of indiana, have invented certain new useful Improvements in Pint-Locks, of which the following is a full and accurate specification.

The object of this my present invention, broadly speaking, is to provide means for locking nuts in engagement with their bolts, to'provide construction which will be neat and attractive in. appearance, strong and durable in constructionyeasily operated and controlled, and which can be manufactured and sold at a comparatively low price.

Morespeci'lically stated, my object is to provide means, in combination with a rela tively med colt having a longitudinally disposcu channel extending across its threaded portion, of a non-rotatable washer contact able with the outer face of the nut, with means for engaging the nut with the washer whereby the nut may not be inadvertently removed, but at same time having means whereby the nut may he removed when desired without breakage, distortion, or other damage to any of the parts.

Other objects and particularadvantages will be brought out inthe course of thefollowing specification, and same will be evident from the accompanying drawings, in

Which Figure l is a plan view of my invention in operative position with relation to the tired element. Fig. is a die-grammatical view showing the contact-face of the washer, with an cdgewise eievation thereof in projection. Fig. 3 central longitudinal section of the invention applied.

face views o'l. the nut, showing two forms for the teeth on the extension thereof.

Similar ti .iracters denote like throughout the scv rel vie The construction and operation or" my invention quite siniple, and i will now take up the dos tion thereof in concrete detail, in which 1 will rel'cr to the several parts and their intended operation briefly and as comprehensively as l nuiy.

In the drawings the letter A refers to a fixed element through which the bolt passes.

The letter B denotes a bolt stem, hz'tving the head 1) formed integral therewith in the nortion of the StLlll. is threaded, substantially Specification of Letters Patent.

And Figs. 4 and 5 are Patented May 5, 1908.

I as shown. Extending from the outer end;

' inward longitudinally of the bolt stern and along one side or, the periphery thereof, .isa

channel pearing. v

The letter C denotes a not of any desired irom the nut, formed integral therewith, and located around the central aperture thereof, is a projection C which is i'nth'e natureof a ring formed integral with the nut proper, and having a plurality of teeth or Spurs (1 'radi-i sting from the outer end thereof as shown. Said teeth maybe formed square, as shown in Figs. 1, 3 and 5, or they may he, preferably,

from the inner periphery of the washer E is a the c iannel b to revent the washer E from rotating indepen" ent of the bolt stem. Extending out radially from the outer eriphery of the washer E are two unequa yspa'ced arms, 6 and 6', each adapted to fit in be tween either two of the teeth d, and each having a T-head adapted to fit inthe space between. the teeth and the face of the nut C, as shown in FY. 1.

In practice t. is not may he run on the bolt and tightened in the usual manner, after wl iich the washer E is placed over the end of the bolt and 1 the projection C of the not, the prong c of course sliding in the channel Zr and finall extending in under the not as shown. now bend the arms ce back to the position shown in Figs. 1 and 3, being atright' course will prevent the nut from being turned in either.direction. Or the teeth Deformed as shown in Fig. it is evident that the nut may be turned in one direction, to tighten it, but it cannot be turned in the opposite dib for the purposehereinafter ap-f V i I formed between the teeth which are for the TZ'Ollgllt up against the face of angles to the face of the washer, which of contour, adapted to be run on the threaded ortion of said bolt. Extending outward.

' beveled oil on one side forming the triangular as is the outside diameter of the projectioniC.

Pro ecting inwardly in an axial direction pron e, which'is adapted to fit and-slide in rection, toloosen it; also if the washer and its rejections which are integral therewith be orfned of spring steel, or the like, then in turning the nut to tighten it the arms e'-(' will slide over the inclines of the teeth (1 and engage ratchet-like to prevent the not from turning in the opposite direction.

I desire that it be fully understoml that various changes may be made in the details of construction from that herein shown and described, Without departing from the spirit of my inventionor sacrificing any of the 2idvantages thereof which are new and useful.

Halving now fully shown and described my invention, and the best means for its eonstruc-tion tome known at this time, What l.

' claim and desire to secure by Letters Petent of the United States, is

The combination with a bolt, of a nut screwed thereupon and provided at its outer portion with a reduced projeqtion of circular conformation, said projection being provided at its peripheral portion with extending in arranged in SpiM'P/(l relation, and 11V (lll'lllill' locking member of substantially the same diameter as the projvvtion oi the nut mid having on inwardh extending tongue to interlock with the bolt to prevent rotation ol' said member, the limiting member also haw ing integral arms projecting from its ()HHY' portion and henlat suhslz ntinlly :1 right an gle thereto so a In he received l)(l'\\'("ll t1tljncent lugs of the nut projection, said arms being provided with Tshnpo .l heads (ll;l,f-- ing the inner sides of the lugs showmentioned to prevent (llSPliHOHHlll oi the l'I)('l ing member.

In testimony of whivh l haw hormmio subscribed my name in the presenw oi' l's'w suhscrihing witnesses.
